    Default Stumped on 02 sensor ???

    Hi folks, Dan here again with a new problem. I have a 1997 Jeep Cherokee, 4.0 engine, auto trans. Check engine light came on today and my code scanner gave me P0132 which means problem with O2 senor. Went NAPA and bought both sensors and replaced them, I used a little dielectric grease on the connecters when I put them in. I checked the 15amp fuse in the main power box under the hood. It checked fine and I don't know if there is a second fuse or not. I still have a check engine light (code P0132)and my scanner won't clear it, I have checked the wiring as much as I could and have not found anything wrong. Someone might check my part numbers because the new rear sensor is smaller in size than old the one. I have not probed any wires for power yet.
    NAPA part numbers:
    Front NGK 23151
    Rear NGK 23099
    Any ideas would be great and thanks for the help.

    Hey Dan.

    If your code scanner will not clear the codes maybe try resetting the computer. Take both battery cables off and hold them together for about 30 seconds. This should clear all the codes out of the computer and reset it to factory settings. It may run crappy for a little while but after 10-15 key on-off cycles it should be running fine. Then if an O2 sensor is bad it'll throw a code again based on factory parameters.
